“Same lofts as the MP-53 but less offset in the short irons and a smaller footprint - a rung-3 iron for the better player who wants a touch of MP-52-family forgiveness without looking like it.”

The MP-59 pushed Mizuno's forged half-cavity concept a step further than the MP-58 by forging a titanium muscle insert into the back cavity, lightening the head enough to grow the sweet area roughly 5% without adding bulk. Mizuno used the identical loft set as the MP-53 sitting alongside it, but pulled offset out of the short irons and shrank the footprint, so the 59 read as the tidier, more tour-shaped option of the pair for a player who wanted a hint of MP-52-family forgiveness without it showing at address. Stock shaft was True Temper Dynamic Gold S300 with Golf Pride M-21 grips, and reviewers called it one of the stronger players' iron releases of 2012 - forgiving enough for a good miss, but still rewarding a center-face strike with genuine forged feel.

It earned real trade-press praise on release - MyGolfSpy ran a dedicated 'Ultimate Review' feature and GolfWRX gave it a strong editor review - and GolfWRX forum threads asking 'anyone still using MP-59s?' show a small persistent user base years later. That is a step above ordinary commodity status, but it never developed the sustained 'why are they so good' collector-hunt reputation of a true cult classic like the MP-32; it is a well-regarded, occasionally-remembered players iron, not a chased one.

Low-to-mid handicap players who already strike the ball consistently and want a bit more margin than a pure cavity or blade without changing the look at address. A mid-to-high handicapper chasing real forgiveness or extra distance should look at a game-improvement or players-distance iron instead - this set won't bail out a poor strike the way a modern GI iron will.

• Forged a titanium muscle directly into the cavity to grow the sweet area roughly 5% versus the preceding MP-58
• Shares its loft set with the MP-53 but uses less offset and a smaller footprint in the short irons
• Stock shaft was True Temper Dynamic Gold S300 with Golf Pride M-21 58-round grips
• MyGolfSpy published a dedicated 'Ultimate Review' feature on the set in 2012, and GolfWRX's editor review was positive
• Lofts are cited as 3-iron 21 degrees / PW 46 degrees by contemporary retailer specs, carrying traditional, un-jacked 2012-era lofts.
• Succeeded in Mizuno's forged players lineage by the MP-64

Released into the same 2012 players-iron class as the Titleist AP2, Callaway RAZR X Muscleback, and TaylorMade Tour Preferred CB, and sat as the more forgiving sibling to the MP-53 within Mizuno's own forged lineup. It descends from the MP-58 and was itself succeeded in Mizuno's line by the MP-64, part of the steady MP-5x generational churn.

Realistic 2026 private-party sets run roughly $150-300 depending on shaft and wear - a GolfWRX seller moved a set for about $140 in 2020, while trade-in aggregators cite an average of $350, which sits closer to a retailer buy-back estimate than a street price. It holds modest value as a still-respected forged players iron but is not a collector piece.
